Single Logout

A mechanism that allows users to log out from all applications in a Single Sign-On (SSO) environment with one action.

Description

Single Logout (SLO) is a crucial feature in Single Sign-On (SSO) systems that enables users to end their session across multiple applications simultaneously. When a user logs out from one application, SLO ensures that the user is automatically logged out from all other connected applications without the need for additional log-out actions. This enhances user security by minimizing the risk of unauthorized access if a session is left open in another application. For instance, in a corporate environment using SSO, if an employee logs out of their email service, they will also be logged out of their document management system, HR portal, and any other integrated services. This feature is particularly beneficial in environments with multiple applications accessed regularly, such as in educational institutions or large organizations. By streamlining the logout process, SLO improves the user experience and strengthens overall security protocols.

Examples

  • A user logs out of Google Workspace, automatically logging out of Google Drive, Google Docs, and other related services.
  • In a corporate setting, an employee logs out of their Salesforce account, which also logs them out of connected applications like Slack and Zoom.

Additional Information

  • SLO is essential for compliance with data protection regulations, ensuring that user sessions are not left active unintentionally.
  • Implementing SLO can involve complex configurations, as it requires coordination between multiple service providers and identity providers.
